I think you still pretty much get the concept of const.
It means the value of yyy cannot be changed after initialisation.
To actually see it used in methods like this.. I assume the example
you gave is a bit 'stripped down' :p
If I get it correctly, everything is ActionScript is passed by
reference, so to expand your example a bit:
function xxx() {
const yyy:Number = 99;
abc(yyy);
}
function abc(zzz:Number) {
zzz *= 10;
}
Not big of an example, not even sure if it's correct. But when this is
done I assume an error will be thrown, saying that the assignment to
zzz in function abc is illegal for the argument yyy, being const.
However this is an assumption, based on how I used const in other
programming languages. I have no experience with it in AS
